Description
Technical field
The utility model relates to bolter equipment, especially a kind of thorn and coal fines fiber separator of trapping of filter screen combed.
Background technology
In coal gasifying process, much technique needs first raw coal to be worn into coal dust, then sends into gasification furnace by burner and gasifies.Due to reasons such as raw coal and transport storages, in the coal dust grinding, be mixed with fiber different in size, easily block Pneumatic conveying pipeline or in burner place bonding, affect the operation of system long-term stability.In system, increase Celloco fractionator Celloco equipment, can effectively isolate fiber, improve coal dust purity.
At present, the comb filter structure of coal fines fiber separator generally all adopts the double-layer separating structure of comb thorn combing and grid screen.Grid is the circular sieve plate of combined type, waits piecemeal to form by 3～5.Comb thorn bar is strip member, arranges the comb thorn of needle-like towards upper surface length direction at interval of 3.5～4.5mm, comb thorn diameter 2～3mm, the long 50～75mm of comb thorn.Comb thorn bar and be radial arrangement, the comb thorn on comb thorn bar is towards 10～15 ° of arrangements of direction of rotation inclination.When the rotation of comb filter structure, first the comb thorn with 10 °～15 ° of angles of lead carries out combing to coal dust, and the long fibre combing out slides to comb thorn root along angle of lead, and grid sifts out short fiber and the velvet-like fiber that comb thorn does not clear out.Once the accumulation of fibers of comb filter structure comb filter, to set amount, is removed from clean-up port after shutdown.
There is following problem in the Celloco fractionator Celloco of prior art: equipment is vertical structure, and coal dust flows from top to bottom, and comb filter structure is for horizontally rotating, and combs thorn bar and is radial arrangement, is difficult to fully contact with coal dust, and purification efficiency is lower, in actual motion, because fiber is just wrapped in comb thorn, do not carry out separating treatment, comb thorn surface smoothing, the long fibre that combing goes out is sliding to after comb thorn root, due to the impact of coal dust and the multiple action of rotational structure, be easy to and comb thorn and separate, again sneak in coal dust, fiber is present on coal dust passage always, agglomerating fiber causes grid often to occur to stop up and affects coal dust flux, stopping state is easy to spread to whole cross section, above grid, pile with coal dust, kill drive unit, cause Whole Equipment to shut down, grid is paved with whole cross section, in the situation that generation obstruction cannot be rotated, only depend on an access door coal dust of all accumulations cannot be removed, increase greatly maintenance worker's labour intensity, the system that simultaneously affects is normally moved.

Described housing is provided with the nitrogen injection system of fiber injection tube and pulverized coal injection blowpipe composition, and fiber injection tube is arranged on cylindrical shell top and spout towards fibre pipe; Pulverized coal injection blowpipe be separately positioned on coal pipe and fibre pipe and spout towards filter screen.
Comb thorn length on described comb row is 300mm, and comb thorn spacing is 20mm.
On two bifurcated housings of described beveled cone, be respectively equipped with peep hole.
Described cylindrical shell is provided with access hole.
The utility model has the mobile direction rotation of the contrary coal dust of comb thorn row compared with prior art, comb thorn row fully contacts with coal dust, greatly improves arresting efficiency, prevents that coal dust from building bridge on filter screen, effectively avoid the fiber having separated to mix with the secondary of coal dust, filter screen is difficult for stopping up, and simple in structure, the trapping ability of coal dust fiber is strong, purification efficiency is high, operation, easy to maintenance, reliable operation, the service life of having improved equipment.
